Question about constructors

[enduser000]

Hello again,
I have a question about constructors.
The book I am reading references the "default constructor defined by C++". It says it is not nessecary to define a constructor if this default one is acceptable. Isn't the default constructor just an unitlized/garbage-value oject? or is that not true? Thanks again,

The default constructor is a function with the same name as the class that takes no arguements/parameters.

More often than now you may want to use your own constructors that take in parameters. But this is saying that you don't want a constructor, then you don't need to write one. It will implicitly run an empty default constructor for you.

e.g

class MyClass {
 MyClass() { } // Default Constructor  
 MyClass(int A) { } // Nth Constructor
};

Some people consider it better coding style to type your own default constructors so as to indicate that you did not leave something out accidentally.

psault: That'd probably fall in the jurisdiction of the 'coding style'/'standard' they were using at the uni/workplace. But yea, I find it a best practice to code a constructor even if it's empty just to be sure.

Thank you all for your time, I will define those in my code from now on for good style.
